As for Pachyrhynchus Knowledge on the genus Pachyrhynchus Germar, species collection of the Hungarian Museum of 1824 has went far beyond in past few years, as the Natural History, 31 species was determined many foreign and local scientists has contributed and are listed herein, moreover, one species were to taxonomy, ecology and distribution (Cabras identified as new to science. Here I provide a list & Rukmane 2016, Rukmane & Barševskis of the species from the HUF. 2016). As this particular genus is admitted to be highly commercial, it is widely present among Pachyrhynchus amabilis species group currently various museum collections.

Apo, Mindanao, the Philippines. In contrast to the detailed morphological description based on a large number of museum specimens labelled as “Mt. Apo”, the precise distribution of this species in Mt. Apo, which is a large mountain mass with the country’s highest peak, has been unknown to date. In addition, nothing has hitherto been known about its ecology. From October to November, 2015, we conducted field sur- veys for Pachyrhynchini weevils along the following three trails in Mount Apo Natural Park: 1) Mandarangan Trail, Barangay Ilomavis, Kidapawan City, Cotabato, 2) Balutakay Trail, Barangay Managa, Bansalan, Davao del Sur, and 3) Bongolanon Trail, Barangay Bongolanon, Magpet, Cotabato.

  • The Functional Significance of Aposematic Signals: Geographic Variation in the Responses of Widespread Lizard Predators to Colourful Invertebrate Prey
    The Functional Significance of Aposematic Signals: Geographic Variation in the Responses of Widespread Lizard Predators to Colourful Invertebrate Prey Hui-Yun Tseng1,2, Chung-Ping Lin1,3*, Jung-Ya Hsu2, David A. Pike4, Wen-San Huang2,5* 1 Department of Life Science, Tunghai University, Taiwan, 2 Department of Biology, National Museum of Natural Science, Taiwan, 3 Department of Life Science, National Taiwan Normal University, Taiwan, 4 School of Marine and Tropical Biology and Centre for Tropical Environmental and Sustainability Science, James Cook University, Townsville, Australia, 5 Department of Life Sciences, National Chung Hsing University, Taiwan Abstract Conspicuous colouration can evolve as a primary defence mechanism that advertises unprofitability and discourages predatory attacks. Geographic overlap is a primary determinant of whether individual predators encounter, and thus learn to avoid, such aposematic prey. We experimentally tested whether the conspicuous colouration displayed by Old World pachyrhynchid weevils (Pachyrhynchus tobafolius and Kashotonus multipunctatus) deters predation by visual predators (Swinhoe’s tree lizard; Agamidae, Japalura swinhonis). During staged encounters, sympatric lizards attacked weevils without conspicuous patterns at higher rates than weevils with intact conspicuous patterns, whereas allopatric lizards attacked weevils with intact patterns at higher rates than sympatric lizards. Sympatric lizards also attacked masked weevils at lower rates, suggesting that other attributes of the weevils (size/shape/smell) also facilitate recognition. Allopatric lizards rapidly learned to avoid weevils after only a single encounter, and maintained aversive behaviours for more than three weeks. The imperfect ability of visual predators to recognize potential prey as unpalatable, both in the presence and absence of the aposematic signal, may help explain how diverse forms of mimicry exploit the predator’s visual system to deter predation.

We performed Bayesian and Maximum Parsimony combined phylogenetic analyses with the main objective of testing higher-level relationships and the naturalness of the major Neotropical and Southern South American (Patagonia and Andes) tribes, including some members from other regions. We compiled a data matrix of 67 terminal units with 63 Entiminae species, as well as four outgroup taxa from Cyclominae, by 3522 molecular (from nuclear 18S rDNA and 28S rDNA, and mitochondrial 16S rDNA and COI gene sequences) and 70 morphological characters. The resulting trees recover a clade Entiminae with a monophyletic Cylydrorhinini and Premnotrypes branching off early.
